A liquid as defined by NFPD and DOT as having a flash point below 37.8°C (100°F).
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- Features of the Scanning Tunneling Microscope
The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...
- What are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...
- Chemical Safety
People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...
- Harmful Chemicals Found In Food
It's getting close to New Years and many people are starting to think about how to lose those extra pounds they managed to gain over the holidays. There are many sorts of diets and fads that have developed over the years from cutting carbs to cutting protein. Everyone has their own opinion as to...
A molecular orbital derived only from an atomic orbital of one atom, lends neither stability nor instability to a molecule or ion when populated with electrons.
Corrects standard electrode potentials for nonstandard conditions.
Equilibrium constant for the ionization of a weak electrolyte.
A solution that obeys Raoult's Law exactly.
Molecular Orbital Theory
A theory of chemical bonding based upon the postulated existence of molecular orbitals.
Pauli Exclusion Principle
No two electrons in the same atom may have identical sets of four quantum numbers.
A class of enzymes found in bacteria within root nodules in some plants, which catalyze reactions by which N2 molecules from the air are converted to ammonia.
Process of reducing the concentration of a solute in solution, usually simply by mixing with more solvent.
The number of repeating corresponding points on a wave that pass a given observation point per unit time.
A measure of the amount of matter in an object. Mass is usually measured in grams or kilograms.
Equilibrium or Chemical Equilibrium
A state of dynamic balance in which the rates of forward and reverse reactions are equal, the state of a system when neither forward or reverse reaction is thermodynamically favored.
A solution that contains a higher than saturation concentration of solute, slight disturbance or seeding causes crystallization of excess solute.
An orgainic ion carrying a positive charge on a carbon atom.
A colorless, nonvolatile solid, XeO3, explosive when dry: in solution it is called xenic acid.
A device used to measure optical activity.
A solid characterized by a regular, ordered arrangement of particles.
Discovered: known in India and China before 1500 and to the Greeks and Romans before 20 BC as the copper-zinc alloy brass
Origin: The name is derived from the German ‘Zink’.
Atomic no: 30
Mass No: 65
Description: A grey metal with a blue tinge. World production exceeds 7 million tons a year, and it is used to galvanise iron to prevent it rusting. It is also employed in alloys and batteries, and as zinc oxide to stabilise rubber and plastics. Zinc is essential for all living things, and is important for growth and development. The average human body contains about 2.5 grams and takes in about 15 milligrams per day. Some foods have above average levels of zinc, including herring, beef, lamb, sunflower seeds and cheese.
Liquefaction of vapor.
Group VIIA elements: F, Cl, Br, I
Numbers that describe the energies of electrons in atoms, derived from quantum mechanical treatment.
